The validity of risk estimates elicited through the Exchangeability Method (EM) has been theoretically questioned because the use of chained questions may undermine the incentive compatibility of the game even when subjects are rewarded with real monetary incentives. In this paper, we examine...

Instream flows may be essential in protecting aquatic species that are threatened or endangered. An economic model of the optimal allocation of water under pure uncertainty is developed, with particular attention paid to the situation when a species characterized by critical depensation is...
